OBJECTIVE: To investigate the expression of CSF3R mutation in acute myeloid leukemia (AML) and analyze its clinical characteristics and prognosis. METHODS: A retrospective study was conducted in 212 patients with AML who were newly diagnosed in the Second Hospital of Shanxi Medical University from January 1th 2018 to June 30th 2021, including 22 patients with CSF3R mutations as mutation group and 190 patients with CSF3R wild type ［66 cases of them were screened by propensity score matching (PSM), as control group］. The early efficacy and survival between the two groups were compared. RESULTS: The median age of patients in the mutation group was 50(17-73) years old, and the ratio of male to female was 1.2:1 The main types were AML with maturation (11 cases) and acute myelomonocytic leukemia (9 cases). Prognostic stratification was carried out according to the risk stratification system of the European leukemia network in 2017, with 16 cases (72.73%) in the middle and high-risk group. At the initial diagnosis, the median count of white blood cell (WBC) was 44.75(1.30-368.71)×10⁹/L, among which 15 cases (68.18%) were >10×10⁹/L, and the median count of platelet (PLT) was 24(4-55)×10⁹/L. CSF3R T618I (68.18%) was a common mutation site, which had concomitant gene mutations, in which CEBPA mutation was the most common (10 cases, 45.45%), but only existed in CSF3R T618I mutation. The CR/CRi rate was 68.18% and 71.21% in the mutant group and the control group (P >0.05), the median over all survival time was 15 months and 9 months (P >0.05), and the median disease-free survival time was 8 months and 4 months (P >0.05), respectively. CONCLUSION Most AML patients with CSF3R mutation are middle-aged patients, the main types are AML with maturation and acute myelomonocytic leukemia, and most of them have middle and high-risk prognosis. CSF3R mutation may not be an independent prognostic marker for newly diagnosed AML patients.

Objective: To understand the status of autism spectrum disorder (ASD) cohort studies and explore the feasibility of constructing ASD disease-specific cohorts based on real-world data (RWD). Methods: ASD cohort studies published by December 2022 were collected by literature retrieval from major Chinese and English databases. And the characteristics of the cohort were summarized. Results: A total of 1 702 ASD cohort studies were included, and only 60 (3.53%) were from China. A total of 163 ASD-related cohorts were screened, of which 55.83% were birth cohorts, 28.22% were ASD-specific cohorts, and 4.91% were ASD high-risk cohorts. Most cohorts used RWD such as hospital registries or conducted community-based field surveys to obtain participant information and identified patients with ASD by scales or clinical diagnoses. The contents of the studies included ASD incidence and prognostic risk factors, ASD comorbidity patterns and the impact of ASD on self-health and their offspring's health. Conclusions: ASD cohort studies in developed countries have been in the advanced stage, while the Chinese studies are still in their infancy. RWD provides the data basis for ASD-specific cohort construction and offers new opportunities for research, but work such as case validation is still needed to ensure the scientific nature of cohort construction.

Odds ratio (OR) and relative risk (RR) are the most commonly used statistical indicators for the estimation of the association between exposure and outcome. In the cohort study with rare outcomes, the estimated OR approximately equals RR, but RR seems more interpretable. The study aims to explore the difference between OR and RR estimated by different multivariate analyses to provide reference for the selection of more appropriate multivariate regression methods and reporting indicators for estimating the association between exposure and rare outcome in cohort studies. This case study used the data from China birth cohort study. Modes of conception and congenital disabilities were regarded as exposure and outcome, respectively. Maternal age, family history of congenital disabilities with clear evidence were included as covariates. Logistic regression, log-binomial regression, and Poisson regression were used to estimate the OR and RR, respectively. Then, OR, RR, and their 95%CI estimated by three regression models were compared. The OR estimated by logistic regression was approximately equal to the RR estimated by log-binomial regression or Poisson regression. However, the RR estimated by log-binomial regression or Poisson regression was closer to 1.00, with a narrower 95%CI. Log-binomial regression or Poisson regression might have non convergence or over dispersion problems. It is recommended to report the RR obtained by log-binomial regression or Poisson regression in the cohort study with rare outcomes if applicable.

BACKGROUND: Normal tension glaucoma (NTG) is a less pressure-dependent type of glaucoma with characteristic optic neuropathy. Recently, the biomechanical mechanism has been thought to account for glaucomatous optic neuropathy to some degree. We intended to compare dynamic corneal response parameters (DCRs) among patients with primary open-angle glaucoma with normal tension or hypertension and controls. The correlations between DCRs and known risk factors for glaucoma were also analyzed. METHODS: In this cross-sectional study, 49 NTG subjects, 45 hypertension glaucoma (HTG) subjects, and 50 control subjects were enrolled. We compared the differences in DCRs using corneal visualization Scheimpflug technology among the NTG, HTG, and control groups. We also analyzed the correlations between DCRs and known risk factors for glaucoma (eg, central corneal thickness [CCT], intraocular pressure [IOP], etc). RESULTS: The maximum inverse concave radius (NTG: 0.18 [0.17, 0.20] mm-1; control: 0.17 [0.16, 0.18] mm-1; P = 0.033), deformation amplitude ratio of 2 mm (DAR 2 mm, NTG: 4.87 [4.33, 5.39]; control: 4.37 [4.07, 4.88]; P < 0.001), and DAR 1 mm (NTG: 1.62 [1.58, 1.65]; control: 1.58 [1.54, 1.61]; P < 0.001) were significantly higher in NTG than in the controls. The integrated radius (IR, NTG: 8.40 ± 1.07 mm-1; HTG: 7.64 ± 1.31 mm-1; P = 0.026) and DAR 2 mm (NTG: 4.87 [4.33, 5.39]; HTG: 4.44 [4.12, 5.02]; P < 0.007) were significantly higher, whereas the stiffness parameter at the first applanation (SP-A1, NTG: 91.23 [77.45, 107.45]; HTG: 102.36 [85.77, 125.12]; P = 0.007) was lower in NTG than in HTG. There were no significant differences in the DCRs between HTG and control groups (P > 0.05). In the univariate and multivariate analyses, some of the DCRs, such as IR, were negatively correlated with CCT and IOP, whereas SP-A1 was positively correlated with CCT and IOP. CONCLUSIONS The cornea was more deformable in NTG than in HTG or controls. There were no significant differences in corneal deformability between HTG and controls. The cornea was more deformable with the thinner cornea and lower IOP.

BACKGROUND: Benvitimod cream, a novel synthetic small molecule, was effective in treating mild-to-moderate plaque psoriasis. We conducted a phase III clinical trial to assess the efficacy and safety of benvitimod cream in patients with mild-to-moderate plaque psoriasis. METHODS: We randomly assigned 686 patients (2:1:1) to receive 1% benvitimod cream, 0.005% calcipotriol ointment or placebo twice a day for 12 weeks. The primary efficacy end points were the percentage of patients with a 75% or greater reduction from baseline in the psoriasis area and severity index (PASI 75) score and with a score of 0 or 1 in static physician's global assessment (sPGA) at week 12. RESULTS: The results showed that 50.4% of patients in the benvitimod group achieved PASI 75, which was significantly higher than that in the calcipotriol (38.5%, P < 0.05) and placebo (13.9%, P < 0.05) groups. The proportion of patients achieving an sPGA score 0 or 1 was 66.3% in the benvitimod group and 63.9% in the calcipotriol group, which were both significantly higher than that in the placebo group (34%, P < 0.05). In the long-term follow-up study, 50.8% of patients experienced recurrence. After retreatment with 1% benvitimod, 73.3% of patients achieved an sPGA score of 0 or 1 again at week 52. Adverse events included application site irritation, follicular papules, and contact dermatitis. No systemic adverse reactions were reported. CONCLUSION: During this 12-week study, benvitimod cream was demonstrated with high effectiveness and safety in patients with mild-to-moderate plaque psoriasis.

【Objective】To measure the orbital fat fraction（FF）of Graves ophthalmopathy（GO）patients and normal individuals with MR Water- fat separation（Dixon） technology ，and to explore the value of orbit MR quantitative fat analysis in diagnosis and treatment for GO patients.【Methods】Forty GO patients and 20 normal individuals who underwent orbital MR imaging were analyzed prospectively from February 2017 to February 2019 in the First Affiliated Hospital of Sun Yat- sen University. All participants received bilateral orbital MR examination with oblique coronary FSE T2- weighted imaging combined with two-point Dixon technique，and then the signal intensity values of ipsilateral extraocular muscles and lacrimal glands on water and fat phase images were measured to calculate FF. The differences of mean FF between the two groups were evaluated，and the correlation between FF of GO and TRAb，CAS score，and the course of GO were conducted by Spearman rank correlation analysis. 【Results】 The median FF of extraocular muscles in GO patients was higher than that of normal individuals，and the result showed a statistically significant difference（P < 0.05）， while the FF of lacrimal glands in the two groups showed no statistical difference. The FF of extraocular muscles in the GO group were correlated with TRAb，CAS score and the course of GO（P < 0.05），especially the course was more correlative.【Conclusions】The fat content of extraocular muscles in GO patients were higher than that of normal individuals ，and there was a positive correlation in the fat content among TRAb，CAS score and the course of GO，suggesting that MR fat quantitative analysis may provide a new reference indexes for the evaluation of clinical staging ，curative effect assessment in GO patients.

OBJECTIVE: To investigate the expression of CD44, CD87 and CD123 in acute leukemia and its correlation with cellular immune markers. METHODS: A total of 166 patients with acute leukemia (AL) admitted from May 2014 to February 2017 were enrolled in AL groups. Among these patients, 100 patients suffered from acute myeloid leukemia, 50 patients suffered from acute lymphoid leukemia, and 16 patients showed B/medullary phenotype. At the same time 50 patients with non-acute leukemia were enrolled in the control group. 5 ml of fasting venous blood collected from the patients in each group, and the percentage of CD44, CD87 and CD123 cells was determined by three-color flow cytometry. Symptomatic chemotherapy was given to the patients with confirmed acute leukemia, and the remission was evaluated after 2 treatmen courses. The Complete remission (CR) was recorded and the percentage of CD44, CD87 and CD123 cells under different curative efficacy were recorded. The correlation of the prognosis patients with CD44, CD87 and CD123 was analyzed by SPSS Pearson correlation analysis software. RESULTS: The positive rates of CD44, CD87 and CD123 in AL group were all higher than those in the control group (P＜0. 05). The positive rates of CD44 and CD123 in acute myeloid leukemia group were higher than those in acute lymphoblastic leukemia group and B/myeloid phenotype group (P＜0. 05). The positive rate of CD44 in acute lymphoid leukemia group was higher than that in B/medullary double phenotype group (P＜0.05). The treatment in the patients of AL group was successfully completed. 132 patients reachel to CR and 34 patients to PR+NR after 2 courses. The positive rates of CD44, CD87 and CD123 in CR patients were lower than those in PR+NR patients (P＜0.05). The results of SPSS Pearson correlation analysis showed that the prognosis of patients with acute leukemia negatively correlated with CD44 and CD87 (P＜0.05). CONCLUSION The expression of CD44, CD87 and CD123 in different phenotype of acute leukemia are different, which correlateds with prognosis. The determination of CD44, CD87 and CD123 can be used to evaluate the prognosis of patients for the reference of clinical treatment.
